Specification of Letters Patent.

Application filed July 22, 1912. Serial No. 710,900.

Patented Dec. 10, 1912.

To all whom it may concern: Be it known that I, ARNOLD ZUKOR, a citizenof theUnited States, and resident of whistle, etc. 15.

' taken through 5 5 the city York and State of New York, have maudiblealarm in of New York, in the county of New vented certain new and usefulImprovements in Burglar-Alarms, o f'which the following is aspecification.

The present inventlon relates to burglar alarms. I Devices of this typeusually produce an ,that: they actuate, for instance It isv obvious thatpersons of defective hearing are liable not to perceive the sound of thebell, and sometimes persons asleep are notawakened even by the veryintense sound ofa bell or whistle.

One of the objects of the present invention -is to obviate thesedefects, and to provide a burglar alarm which can be readily adapted toa door or window, in such a manner that the. opening of the door orwindow will produce an alarm in the form of a water spray issuing from aspray nozzle, Wl'llCh is arranged above the bed occupied by the personto be awakened by the opening of a door or window in the house.

With these and other objects in view, which will more fully appear asthe nature of the invention is better understood,- the same consists inthe combination, arrangement and construction of parts hereinafter fullydescribed, pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that many changes may be madeinthe size and proportion of the several parts and minor details ofconstruction within the scope 'of the appended claims without departingfrom the spirit or sacrificing any of the advantages of the invention.

of the invention is illustrated in the accompanying drawings, in whichFigure 1 illustrates diagrammatically the invention as applied for useFig. 2 is an enlarged front elevation of the means for actuating a cockinserted into .the water pipe; Fig. 3 is a side elevation of a detail ofconstruction shown in Fig. 2; Fig. 4 is a side elevation of theactuating means as applied to'a window; Fig. 5 is a cross section thejamb of the door with the'alarm actuating means in operative poanelectric or other bell, operate a" sition thereon; and Fig. 6 is a sideelevation, partly in section, of a further detail of construction.

In the drawings, the numeral 10 indicates a window, havin an upper sash11 and a lower sash 12. o the upper rail of the sash 11 is detachablyfastened, for, instance by means of a bolt 13 and a wing nut 14, adownwardly extending vertical rack 15, the teeth of which mesh withthose of a gear 16, which is keyed or otherwise attached to a shaft 17,suitably journaled in a bearing '18, the latter being attached to a wallof a room. In a suitable manner is fastened by a bolt 19 and a wingnut20 to the lower rail of the lower sash 12 an upwardly extending verticalrack 21, in mesh with the gear 16. The racks 15 and 21 are guided intheir movement by guards 22 and 23, respectively, and engage the gear 16upon diametrically opposite portions thereof so that, upon the downwardmovement of the sash 11 or upon the upward movement of the sash 12, thesaid gear will rotate in the same direction, as indicated by the arrowin Fig. 4 of the drawings.

To the end of the shaft 17 is secured a cam 24, adapted to actuate asubstantially vertical rod 25, which is slidably arranged in guides 26,26, the lower end of said rod bearing against the actuating lever 27 ofa faucet. 28, which is mounted upon a water pipe 29. A spring 30,bearing against the lower guide 26 and against a washer 31, which isattached to the rod 25, tends to hold the latter continuously inengagement with the cam 24. From the faucet 28 leads a plpe 32 along theWalls of the room to a bed 33, and terminates in a spray-nozzle 34,which is arranged a substantial distance above the bed. From the pipe 32branches out a pipe 35, leading through the wall 36 of the building andterminatin outside of the building in a spray-nozzle 3% for a purposehereinafter to be described. A.,cock 38 is arranged immediately abovethe spraynozzle 34, and a cock 39 in rear of the pipe 35.

For the'protection of the door a similar device is used, as shown indetail in Fig. 5 of the drawings. The door is indicated by the numeral40 and its jamb by the numeral 41. In the jamb is formed a recess 42, inwhich is slidably' arranged a rack keyed to a shaft 45. Thisshaft isrotatably mounted in bearings 46, 46 and carries upon its end a cam 47,adapted to actuate a rod 48, slidably arranged in guides 49, 49 andbearing against a substantially horizontal extension 50 upon the rod 25above mentioned. A s ring 51, bearing against the lower one o the guides49 and a ainst a washer 52 upon the rod 48,-tends to orce the latterinto engagement with the cam 47. In the recess 42 is arranged behind therack 43 a spring .53, the latter having a tendency to move the rack 43outward and to rotate thus the ear 44 and the shaft 45 upon which saigear is mounted. Near to the upper edge of the door is attached a plate54, which is adapted to engage an upwardly extending projection 55 uponthe rack -43, to keep thereby the spring 53 in its com pressed state andthus the rack 43 from actuating the gear 44. A keeper 56 is attached bymeans of a bolt 57 and a wing nut 58 to the jamb in engagement with theprojection 55 upon the rack 43. This keeper is brought into theposition'shown in Fig. 5 of the drawings in daytime, that is when it isnot necessary to protect the door, in which case obviously the door canbe opened and the rack 43 will be retained agamst the action of thespring 53 in its recess. When it is intended to protect the door, of

course, the keeper 56 is swung about 90 upward, that is to say out ofengagement with the projection 55 upon the rack 43.

The operation of this device is as follows: To bring the parts of'thealarm into their operative positions, first the cocks 38 and 39 are setto open a communication between the faucet 28 and the spray-nozzle 34.The racks 15 and 21 are attached by the wing nuts 14 and 20,respectively, to the upper and lower sashes of the window. The keeper.56 is then disengaged from the projection 55 upon the rack 43, wherebythe device is ready for operation. It is to be observed that at daytime,or at times when the house is not to be protected by the alarm, theracks l5 and 21 are disengaged from the sashes of the window. If thesashes of the window are'lowered or raised from outside by unauthorizedpersons, rotation will be imparted to the gear 16 and thus to the shaft17, whereby the cam 24 will act upon the rod 25, which in turn willrepress the operating lever 27 of the faucet 28, causing thereby a flowof water toward and to the spray-nozzle 34. Alarm is thus given. Shouldthe door be opened, the plate 54 will be removed from the projection 55ofthe rack 43, permitting thereby the spring 53 to act and to rotate thegear- 44. The rotation of the gear 44 causes an angular movement of thecam 47 and a shifting movement of the rods 48 and 25, which result in anopening of the faucet 28. After the person is awakened, the flow of theWater can bestopped by turning the cook 38 in the proper directlon. Ifthe person leaves the house at daytime, the cook 39 is closed and thedevice applied to the window only. If then the window is opened, waterwill flow through the pipe 32 into the pipe- 35, and through thespray-nozzle 37' to the outside ofthe building, indicating thereby theentrance of unauthorized persons into the building.

For further protection, a sash 60 may be slidably arranged in the windowframe. This sash is connected by means of a bracket 61 with the rack 21.The sash 60 is covered by an iron lattice-work. The raising of the sash60 will actuate the gear 16 in the man ner above-described.

\Vhat I claim is 1. A burglar alarm comprising a water pipe terminatingin a. spray-nozzle leading from a supply'of Water, a faucet providedwith a lever pivoted thereto for actuating its plug, said faucet beinginserted into said pipe for controlling the flow of water thereto, a rodshiftably arranged upon the wall of a room bearing against said lever, acam adapted to shift said 'rod, a gear operatively connected to saidcam, and a rack meshing with said gear adapted to impart rotation to thelatter by the opening of a device closing an entrance to the room.

2. A burglar alarm comprising a water pipe terminating in a spray-nozzleleading from a supply of water, a faucet provided with a lever pivotedthereto for actuating its plug, said faucet bein inserted into said pipefor controlling the ow of water thereto, a rod shiftably arranged uponthe Wall of a room bearing against said lever, a cam adapted to shiftsaid red, a gear operatively connected to said cam, and a rack meshingwith said gear carried by a device closing an entrance to the room andadapted to impart rotation to said gear by the opening of said device.
